Echocardiographic diagnoses of congenital atrial appendage aneurysm: from fetus to adult

To summarize the echocardiograhic features of atrial appendage aneurysm (AAA) in fetuses, children and adults and evaluate the value of echocardiography in the diagnosis of AAA. The AAA echocardiographic features of 6 fetuses, 1 child and 4 adults were retrospectively analyzed. And the diagnoses were confirmed by autopsy, postnatal follow-ups, computed tomography (CT) and surgery. Left atrial appendage aneurysm was more common than right atrial appendage aneurysm. AAA had the same echocardiographic characteristics in fetuses, children and adults. And it was usually combined with other complex cardiac malformations in fetuses while single cardiac abnormality was predominant in children and adults. Fetuses, children and adults with AAA may be found by echocardiography in time so that echocardigraphy has an important role in diagnosing AAA.

無症候性左心耳瘤の病理組織学的検討

左心耳瘤（left atrial appendage aneurysm, LAAA）は，1938年にSemansとTaussigにより初めて報告された非常に稀な疾患で，先天性のものの多くは原因不明である．小児期に無症状で発見されると，将来的な不整脈，胸痛，呼吸困難，血栓塞栓症などの合併症予防のために外科的切除を行う．今回我々は，急性気管支炎の際に胸部レントゲン写真で異常を指摘された2歳女児におけるLAAAの症例を経験した．経胸壁エコー，経食道エコー検査を行い，瘤内や心耳内血栓を否定した．また造影CTにて周囲に異常構造がないことを確認した．手術により切除した病理組織において，三層構造は保たれていたが，筋層の菲薄化と粘液性変化がみられた．恒常性を維持させられないほどの組織障害が生じたことが，瘤の原因となりえた可能性が示唆された．

Incidentally detected congenital left atrial appendage aneurysm

A 22-year-old male patient was referred to us for cardiac computed tomography (CT) angiography since chest radiograph showed prominent left cardiac border. Patient was asymptomatic and chest radiograph was done as a routine health checkup. Laboratory findings were within the normal range. Electrocardiograph (ECG) showed normal sinus rhythm. Cardiac CT angiography revealed a 9×8×6 cm sized left atrial appendage aneurysm communicating with left atrium (Figs. 1a and 2). There was associated partial thrombus within the aneurysm (Fig. 1b). Echocardiography showed left atrial aneurysm with partial thrombus and normal cardiac valves. Due to the potential risk of embolism, the patient was referred for surgical resection of the aneurysm.

Left atrial appendage aneurysm: a systematic review of 82 cases.

Aneurysm of the left atrial appendage is rare. We sought to systematically review the published literature on left atrial appendage aneurysm (LAAA) to address its demographic features, clinical characteristics, treatment, complications, and outcomes. A systematic electronic search of Medline, PubMed, and EMBASE for case reports, case series, and related articles of LAAA published from 1962 until July 2013 was carried out. Statistical analysis was done using SPSS version 20.0. Logistic Regression Analysis was used to identify the independent predictors of LAAA-related thrombus formation and embolism. Eighty-two cases of LAAA were identified. There was a slight female preponderance and most of the patients presented in their third decades. Palpitation, dyspnea or both were most common clinical symptoms associated with LAAA. Echocardiography was the main diagnostic modality used and the mean size of aneurysm was 7.08 ± 3.03 × 5.75 ± 2.36 cm. Surgical resection of the aneurysm was performed in most patients with favorable results. Systemic embolism and atrial tachyarrhythmias were the two common complications associated with untreated LAAA. Presence of atrial fibrillation/flutter was the only significant predictor of thrombus formation/embolic events. Aneurysm of left atrial appendage is rare and often an incidental diagnosis during echocardiography. It is important to recognize this entity since it is associated with cardiovascular morbidity and mortality by predisposing to atrial tachyarrhythmia and thromboembolism. Surgical resection is the standard of treatment in the current literature. Medical management is directed toward the treatment of thromboembolism and atrial tachyarrhythmia.

An incidentally diagnosed asymptomatic congenital left atrial appendage aneurysm

Left atrial appendage aneurysm is a rare cardiac anomaly. It can be congenital in origin or acquired secondary to inflammatory or degenerative processes. As it may cause potentially lethal arrhythmias or thrombi, surgical treatment is needed immediately after the diagnosis. In this article, we report a case of an asymptomatic three-year-old boy with a congenital left atrial appendage aneurysm. The patient was successfully treated with surgical resection of the aneurysm.

Giant Congenital Aneurysm of the Left Atrial Appendage

> Aneurysm - Atrium - Atrial appendage Left atrial appendage aneurysm, either congenital or acquired, is a very rare anomaly. It is caused by congenital dysplasia of the atrial muscles, or it may be the result of other systemic or heart diseases. This anomaly is mostly asymptomatic and usually diagnosed incidentally, but occasionally it may present with atrial tachyarrhythmias and/or thromboembolic events. This report describes the case of a patient with giant congenital aneurysm of the left atrial appendage.

Off-pump snare technique for congenital left atrial appendage aneurysm

Left atrial appendage aneurysm is an extremely rare anomaly and as such has been rarely imaged or seen intraoperatively with very little accumulated management experience. The available scant published literature stresses resection on cardiopulmonary bypass as the safest and by far the most commonly applied technique. We suggest a novel alternative imaging-guided management utilising an off-pump tourniquet snare technique under live transoesophageal echocardiography.

Left atrial appandage giant aneurysm and thrombus compressing to the left ventricle

Left atrial appendage aneurysm is a rare anomaly, which usually present in adulthood. Most patients are asymptomatic, however they often suffer from palpitations which usually grows out of atrial tachyarrhythmias. The main manifestation of the disease is usually systemic embolism. The major manifestations of such aneurysms are an abnormal cardiac silhouette; therefore cardiac tumors or pericardial cysts should be considered in the differential diagnosis. Various imaging techniques are useful in diagnosis and allow the differential diagnosis among other pathologies. Resection of the aneurysm is the recommended form of treatment. In this article, we present a 66-year-old female case with aneurysm of the left atrial appendage. The patient was admitted with atrial fibrillation and recurrent systemic embolizations. Diagnosis was based on transthoracic and transesophageal echocardiography. The patient was treated by surgical resection of the aneurysm under extracorporeal circulation.

Gokoglan, B. Bugan, S. Firtina, A. Iyisoy, H.K. Kabul. Department of Cardiology, Gulhane Military Medical Academy, Ankara, Turkey; Department of Radiology, Gulhane Military Medical Academy, Ankara, Turkey; Department of Cardiology, Malatya Army Hospital, Malatya, Turkey; Department of Cardiology, Erzincan Army Hospital, Erzincan, Turkey Objective: The two most common pulmonary venous (PV) anomalies are the presence of aright middle PV and common left trunk. Herein, we report a patient with left common pulmonary venous ostium misdiagnosed as left atrial appendage aneurysm on echocardiography. Methods: A 67-year-old female with a medical history of hypertension admitted to our outpatient department for palpitation and dyspnea on exercise. She was advised to undergo routine echocardiography, which showed dilated left ventricle, decreased left ventricular ejection fraction (25%), moderate mitral regurgitation and left atrial appendage aneurysm. She was referred to cardiac computed tomographic angiography (CTA) for delineating anatomy. Results: CTA revealed an unusual pulmonary venous anomaly consisting of a left-sided common and unusually large ostium of left pulmonary veins draining to left atrium and normal coronaries. Conclusion: Cardiac anatomic variants has become increasingly important as the number of radiofrequency ablations has increased. The definite differentiation of pulmonary common ostium from an atrial appendage aneurysm could be made with transesophageal echocardiography, computed tomography and magnetic resonance imaging.

The dangerous fifth chamber : congenital left atrial appendage aneurysm : case report

Aneurysms of the left atrial appendage are extremely rare. Enlargement of the left atrial appendage can be congenital or acquired. Dysplasia of the left atrial muscles leads to congenital left atrial appendage aneurysm and usually presents as atrial tachyarrhythmia or embolic events in the second or third decade of life. We report a case of an asymptomatic 12-year-old child with a congenital left atrial appendage aneurysm. Transthoracic and transoesophageal echocardiography demonstrated a large left atrial appendage aneurysm without thrombus or spontaneous echo-contrast. The patient was successfully treated with surgical resection of the aneurysm.
